I I Letters Patent No. 69,631, dated October 8, 1867.

IMPROVED RAILWAY WATER-BLEVATOR.

TO ALL'WHOM IT MAY CONGERN:

Be it known that I, MARTIN S. COLLAR, of Marquette, in the county of Green Lake, and State of Wisconsin, have invented a new and useful Improvement in Pump; and I do hereby declare Vthat the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use tho same, refcrence being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is atop or plan view of my improved pump, showing its connection with the railroad track.

Figure 2 is a detaill view of one of the irons acted upon by the car-wheels.

Figure 3 is a vertical longitudinal section taken through the line a: x, tig. 1.

Figure 4 is a vertical section of my improved pump-valve, taken through the line y y, tig. 5.

Figure 5 is a top view of the same.

Similar letters of reference indicate like parts.

My invention has for its object to so construct and arrange a pump, in connection with arailroad track, that the passage of a. train of cars will raise the water into a reservoir; and it consists in the combination and arrangement of parts by means of which the pump is operated by the wheels of the passing ears, and in the construction ofthe pumpvvalve.

A is the pump-barrel or pipe leading down into the well. B is a pipe leading from the pump to the reservoir C. D is a pipe conducting the surplus water back into the well. E is the piston-rod, and F is the piston of the pump, by the' action of which the waterv is raised through the pipe A, and forced through the pipe B into the reservoir C. G are the valves, one of which is placed in thc pipe A., to prevent thc water from flowing back into the well, and another of'which is placed in the pipe B, to prevent the water from flowing back through the said pipe. The valve Gismade'in the form of a hollow cone, divided into two halves or leaves gl, as shown in the drawings. These halves or leaves gl'are hinged to the valve-seat 72 in such a way that the water, as it rises through the pipes, will force the said leaves back against the sides of the pipes, so as to allow a large stream of water to pass through tbc pipe. The upper end of the piston-rod E is pivoted to the ond of the long arm of the bent lever H, which is pivoted between the `timbers I, leading from the pump to the railroad track. To the lower end of the short arm of the bent lever H is pivoted the end of the connecting-rod or bar J, the other end ot' which is pivoted to one arm of the equal-armed bent lever K, the other end of which is connected lto the middle point of the cross-bar L by the connecting-bar M. The bar L crosses the track of the road passing under the-sillsN, upon which the rails O are laid, and at its ends is pivoted to the lower ends of the irons P. The irons P pass up through slots or notches in the outer side ilanges of the rail O, so as to be in a position to bo acted upon by the tread or rims ofthe passing car-wheels. The upper ends or heads of the irons P are made in the shape of a double-inclined plane, as shown in iig. 2, so that the ear-wheels can easily pass upon and ovor theln in either direction. It are springs, one end of which is attached to the sills N, and their other ends rest against the under side ofthe heads ofthe irons P, so as to raise them when released from the downward pressure of the passing wheels. If desired, the springs R may be replaced by weights, so arranged as to raise the irons P when released from the passing wheels. By this construction, as each pair ot wheels passes upon the irons P, the said irons are forced down, causing the piston F to descend,lforcing the water that may be beneath it up through the pipe B into the reservoir C, and as the said wheels pass off the irons P, the said irons again riso, raising the piston F, and forming a vacuum in the pump, which is immediately filled by the water forced up by the pressure of the atmosphere upon the water in the well. Thus the passage of each pair of wheels pumps one stroke of the pump. It' more water is raised than required for use, the surplus water is conducted back into the we'll by the pipe D, and the reservoir is thus kept from overflowing.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination and arrangement of the irons P, springs R, cross-bar L, bar M, bent lever K, connecting bar J, bent lever H, and piston-rod E, operating as described,.for the purpose specified.

2. In combination with the above, th'e conical valve G, constructed as described, consisting of the leaves y, hinged to opposite sides of the seat y2, in lsuch a manner that the water, as it rises through the pipe, will force the leaves back against the sides of the tube, said leaves re-closing by their own gravity, substantially as described, for the purpose specied.

The above specification of my invention signed by me this 12th day of March, 1867.
